Boring 6 hour car journeys
Every Summer, my family would head for Stranraer in Scotland to visit family. It was a six hour journey by car and the family car at the time was a Volvo estate. With my two sisters in the back seats with luggage inbetween them, my brother and I were forced to 'camp' in the boot. We lined it with duvets and pillows and it was a nice little den for us to chill out in during the journey (obviously the parcel shelf was removed). Highly illegal yes, but we never got pulled over. Nice to see how responsible my parents were.

Such was the length of the journey, boredom would soon set in. We would soon grow tired of drawing or doing puzzles, so to entertain our young minds, my brother and I would hold up signs to other cars on the motorway such as 'Nice boobies', 'I just did a poo', 'your face looks like a rat's face', 'we're being abducted, please call Childline', 'your wheel has fallen off' and 'finger my bumhole'. Quite what people thought of this, I have no idea. It was made funnier to us as we had to stifle our laughter from my parents, who would have given us the biggest bollocking had they seen what we were up to.

I used to go to a lot of football matches (see below)...
and we found that we could pass hours on the motorways insulting rival fans with an A3 sized pad and a chisel-tip marker.

good way to pass time
there's only so long you can play "i spy" before a massive fight breaks out.

I know this is going to sound like an Urban Myth, but I can only related as heard on This American Life podcast a week or two back.

A bloke driving down the highway when aggressive police pull him over, get him on his knees with a rifle pointed at his head because his kid had held up a sign saying 'Help, Kidnapped, Call 911'. And someone had.

Clickage for 'finger my bumhole'.

I used to love riding in the boot of the car.
Dad drove us to school in the back of a hired van, once, just so we could leap out of the back, whilst humming the A Team theme.
